SPECIFICATION forming part of Letters Patent No. 288,206, dated November 13, 1883,

Application filed July 19,1883. (No model.)

To (LIZ whom. it may concern.-

Be it known that I, GEORGE Clisslinr, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigall, have invented a new and useful Feed- Water Heater, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to feed-water heaters for locomotive and other boilers, and is an improvement on the device for which Letters Patent of the United States No. 274,561 were granted to myself on the 27th day of March, 1883.

My present invention has "for its object to produce a device which shall possess superior advantages in point of simplicity, durability, and general efficiency; and to this end it consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a front view,showing my invention applied to the firebox of a locomotive.

broken away in order to show the invention cleariy; and Fig. 3 is a transverse vertical sectional view on the linew w in Fig. 2.

The same letters refer to the same parts in all the figures.

A A represent the side walls, B the back wall, and G the front, of the furnace, having the door D.

. E is a pipe extending transversely through the furnace near its rear end, and having its outer ends, which are designated by F F, connected by pipes G G with the steam-dome of the boiler. The pipes or extensions E F are Fig. 2 is a topview of the same, the crown-sheet having been end of the fire-box, and provided with wash- 45 out plugs M, accessible through the front wall of the furnace and registering with the pipes K. Pipe L is connected with the water-leg by means of pipes N, extending downwardly in front of the furnace.

In operation water is pumped through the pipes E into the pipe E, whence it passes through pipes K, L, and N to the water-space of the boiler, being first thoroughly heated in the pipes E, K, and L, which are exposed to the full heat of the furnace. hen pumping is suspended, water enters through the pipes N N from the water-space of the boiler, and the steam that is made in the pipes, L, K and E passes through the pipes G G to the steanidome of the boiler, thus causing the best circulation possible. i

I claim and desire to secure by Letters Patent of the United States- The combination, with a boiler-furnace, of 6 transverse pipes arranged in the same, respectively near the rear and front ends, longitudt nal parallel pipes connecting the said transverse pipes, wash-out plugs registering with said longitudinal pipes and extending from the fronttransverse'pipe through the front wall of the boiler, pipes extending downwardly in front of the furnace and connecting the front transverse pipe with the waterleg, pipes connecting the ends of the rear transverse pipe with the steam-dome of the boiler, and pipes connecting the ends or extensions of the rear transverse pipe with the injectors, and provided with chambers having check-valves, all arranged and operating substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

GEORGE GASSADY.
